Posted on by 2

Hello,
after the sucessful run of desktop flow, triggered by automated child flow, the error ocurtes to set the "Action 'Respond_to_a_PowerApp_or_flow' failed". If i trigger the child flow manualy with all the paramters, the flow run sucessfull and the "Respond to flow" works ans set the time stamp.
Any Idea where the error comes from and to solve it?

    Hi @RS2022 ,

     

    The child flow trigger doesn't have a timestamp property.

    So the workaround is to set a variable to utcnow() and respond to parent flow.

     

    Best Regards,
